摘要： A robust and general method is provided to synthesize noble metal-based amorphous-crystalline heterophase nanoparticles, each having an amorphous noble metal core and a crystalline semiconductor/metal shell or a Janus structure with an amorphous noble metal domain and a crystalline metal domain attached side by side with the amorphous noble metal domain (i.e., snowman-like structure). The as-synthesized heterophase nanoparticles not only exhibit superior activities in diverse catalytic reactions but also show unexpected high stability, which could be used as ideal templates for the seeded growth of other nanostructures, thus show tremendous potential in different applications including electrocatalysis and photocatalysis. With efficiently separated photo-induced electron and photo-induced holes, superior catalytic performance of amorphous nanomaterials, efficient solar energy conversion ability of crystalline semiconductors, as well as the synergistic effect between them, the controlled construction of amorphous noble metal-crystalline semiconductor heterostructures can be a promising route to development of high-performance catalysts towards photocatalytic reactions.

摘要： It has been discovered that mixed-alcohol production can utilize the waste tail gas stream from the pressure-swing adsorption section of an industrial hydrogen plant. Some variations provide a process for producing mixed alcohols, comprising: obtaining a tail-gas stream from a methane-to-syngas unit (e.g., a steam methane reforming reactor); compressing the tail-gas stream; separating the tail-gas stream into at least a syngas stream, a CO2-rich stream, and a CH4-rich stream; introducing the syngas stream into a mixed-alcohol reactor operated at effective alcohol synthesis conditions in the presence of an alcohol-synthesis catalyst, thereby generating mixed alcohols; and purifying the mixed alcohols to generate a mixed-alcohol product. Other variations provide a process for producing clean syngas, comprising: obtaining a tail-gas stream from a methane-to-syngas unit; compressing the tail-gas stream; separating the tail-gas stream into at least a syngas stream, a CO2-rich stream, and a CH4-rich stream; and recovering a clean syngas product.

摘要： An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to produce less fouling sediment. The dual catalyst system more effectively converts sediment-forming precursors to produce sediment that is less fouling than sediment produced using only the heterogeneous catalyst and not the dispersed metal sulfide particles. The dual catalyst system provides for a lower rate of equipment fouling for a given sediment production rate and/or concentration. In some cases, sediment production rate and/or concentration can be maintained or increased while equipment fouling is reduced. In some cases, sediment production rate and/or concentration can be increased without increasing equipment fouling.

摘要： The invention concerns a composition comprising a mixture of zinc sulphide (ZnS) and molybdenum sulphide (MoSx), in which the Mo/Zn molar ratio is in the range 0.01 to 1.9. The invention also pertains to a process for its preparation as well as to its application in photocatalysis and more particularly to its application in photocatalysis for the production of dihydrogen from water (H2O) and/or hydrogen sulphide (H2S) and/or any other source of protons in the presence of a source emitting in the ultraviolet and/or visible spectrum.
